Partially underground (the Turks banned churches from being taller than mosques), this church dates from the 14th century is the most historically important in the city. Its dark interior boasts a stunning wood-carved iconostasis 10m wide and 6m high, built by early-19th-century master craftsmen Makarije Frčkovski and brothers Petar and Marko Filipovski. It's rather tricky to find as its sunken design means it doesn't really look like a church from the outside.
Outside, the Tomb and Museum of Goce Delčev has the remains of Macedonia's foremost national hero. Leader of the VMRO (Internal Macedonian Revolutionary Organisation), Delčev was killed by Turks in 1903.
